Captured using revolutionary four-dimensional scanning technology, scientists have managed to shed light on the world of mammals inside the womb.
As diverse a bunch as they are - elephant, dog, dolphin and penguin are all shown united by their similar stages of development.



Using revolutionary four-dimensional scanning technology, scientists have captured the images for a National Geographic Documentary called 'Extraordinary Animals in the Womb'.
They were captured by using a combination of three-dimensional ultrasound scans, computer graphics and small cameras to document the animals’ development from conception to birth, and give an unparalleled glimpse into a world that few of us would ever expect to see.
The images were also used on a Channel 4 documentary 'Animals in the Womb'.
The documentary explores the marked similarities between very different animals.
